Cable QSFP112 MSI EdgeXpert 400G 0.4m 956-C931-101

QSFP112 Cable MSI EdgeXpert 400G 0.4m

The MSI QSFP cable (part number 956-C931-101) is the official accessory for linking MSI EdgeXpert AI supercomputers built on the NVIDIA DGX Spark platform. It connects the ConnectX-7 ports of two systems with a fast, low-latency link, so you can run larger models across both machines.

Both ends use QSFP112 connectors, with 112G per lane (up to 400G total bandwidth) and PAM-4 modulation, and the cable is 400 mm long. With three such cables you can also join three systems in a switchless ring topology. The cable is sold separately and is not included with the EdgeXpert.

Key features

• Links EdgeXpert systems - Connects the ConnectX-7 QSFP ports of two MSI EdgeXpert systems to build a cluster for larger AI models.
• High bandwidth - 112G per lane with PAM-4 modulation, up to 400G total bandwidth, for fast low-latency communication.
• Length for stacking - At 400 mm (plus or minus 15 mm), it suits systems stacked on top of each other.
• Three-node cluster - According to MSI, three cables connect three EdgeXpert systems in a ring topology without a QSFP switch.
